Question

Solve for s and t. $s-t=3$ & $\frac{s}{3}+\frac{t}{2}=6$

• A. $t=9$ $and$ $s=6$
• B. $t=6$ $and$ $s=9$
• C. $t=-6$ $and$ $s=9$
• D. $t=6$ $and$ $s=-9$

Answer 1

Answer: (B)

$t=6$ $and$ $s=9$

$s-t=3\therefore s=3+tthen\left(\frac{s}{3}\right)+\left(\frac{t}{2}\right)=6or2s+3t=362(3+t)+3t=366+2t+3t=365t=36-6\therefore t=\left(\frac{30}{5}\right)=6thens=3+6=9$
